IMPROVEMENT IN STEAM-ENGINE OIL-CUPS.

'IO ALL WHOM IT MAY CONCERN:

Be it known that I, F'. LUNKENHEIMER, of Cincinnati, in the county ot'Hamilton, and State of Ohio, have invented a new and useful Improvementin Oil-Cups; and I do hereby declare that the followingds a full, clear,and exact description thereof, which will enable others skilled 'in theart to make and use the same, reference being had to the acccmnanyingdrawings, forming part of this specification.

This invention consists in the peculiar construction of the cup, wherebyit isjadapted for the use of tallowand other lubricating material, andwhereby the chamber which contains the oil or'lubricating material ismade air-tight, as will bc hereinafter described.

The drawing represents avertical elevation of the oil-cup, partly insection, in order to show the internal arrangement.

A is the cap. A is the hand-wheel, and A forms the nut.' B is a centralscrew-bolt, irtnly attached to the bottom part of the chamber. C is thechamber which contains the lubricating material. D is the cup.

The cap is formed'of two or more pieces, as represented in the drawing.The part A sets on to the top of the cup',

having a. `groove in its under side, which fits over a projecting flangeon the cup as seen at a. The part Al (represented in blue) forms a nut,and is attached to the part A. There is a groove in the part A whichreceives a ange, which projects from the top of A, and forms theconnection between the parts A A. The part marked A" is formed partly cfbrass and partly of iron or steel, as seen in the drawing. Thelubricating material is placed in the chamber C, and passes down throughapertures e into the cock F. The discharge of the oil or lubricatingmaterial is governed by the cock F, or by the cap, which, when screwedtightly down, forms an air-tight chamber at C, and the oil can only pass`out of the chamber as air admitted. The cap is attached to the cup onlyby the screw B, and it may be screwed down as' tightly as may bedesired. G is the neck, which is attached to the steamchest or cylinder;b represents an aperture, through which the oil passes.

The cock F screws into the oil-cup at d.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- 1. The hand-wheel, nut, .and cap formed ofthe parts marked A, A', and A, arranged Vand combined' subv stantiallyas described.

2. The screw-bolt B, attached to the bottom of thechamber C, by whichthe cup and parts attached to the cup are confined, substantially asshown and described.
